AccZ Spikes

Need some advice on a strange spike on AccZ the quad is flying very but just wanted some advice as to what my be the cause of this spike.

I have included a log file

Issue sorted!!

The quad is a Skyhero Little Spyder and after a bit of investigation turns out one of the speed controllers was not well enough supported up the inside of the arm.

Test 1 and Test 2 shows the difference.
